THE PHYSIOLOGICAL RESPONSES OF CHIMPANZEES TO SIMULATED LAUNCH AND RE-ENTRY ACCELERATIONS

Abstract

Five male chimpanzee subjects were exposed to simulated space flight conditions of launchACCELERATION AND ATMOSPHERIC RE-ENTRY DECELERATION. Heart and respiration rates showed significant differences for the three conditions of launch. The conditions of launch were: launch acceleration only, launch acceleration with vibration and noise, and launch acceleration with noise, vibration, urinary tract catheterization and arterial and venous catheterizations. Physiological responses associated with launch and re-entry differed significantly from the baseline period that preceded each of the launches. Physiological changes associated with re-entry were not as severe as those seen with launch. The subjects recovered from the environmental stressors of both launch and re-entry very rapidly. The resultant responses should be good predictors of chimpanzee cardiac and respiratory activity during the critical acceleration phases of space flight and also serve as a baseline for the study of the effects of weightlessness following launch acceleration and prior to re-entry deceleration.
